VideoView vv = (VideoView) findViewById(R.id.vv);
MediaController mc = new MediaController(this);
mc.setEnabled(true);
mc.show(0);
vv.setMediaController(mc);
vv.setVideoURI(Uri.parse("rtsp://v1.cache5.c.youtube.com/CigLENy73wIaHwkshBA7HCmxtBMYESARFEgGUgx1c2VyX3VwbG9hZHMM/0/0/0/video.3gp"));
vv.requestFocus();
vv.start();

我正在使用这个java代码访问和播放视频请建议一些解决方案，以便我为我的应用程序提供高质量的视频播放。

Thanks in advance

Answer 1

目前的建议是在应用程序的WebView中使用Player。

在未来的某个时候，我们计划发布一个可以处理YouTube播放的原生Android视图，正如在Google I/O 2012会议上所描述的:https://developers.google.com/events/io/sessions/gooio2012/120/
